One type of question can indirectly reveal a lot about a person's personality. Asking someone what they think about other people reveals much about their own personality. The reason is that people tend to see more of their own qualities in others. The generous person sees others as generous and the selfish person sees others as selfish. Dr Dustin Wood, the study's first author, said: "A huge suite of negative personality traits are associated with viewing others negatively. The simple tendency to see people negatively indicates a greater likelihood of depression and various personality disorders." The conclusions come from a series of three studies. In one people were asked to judge the positive and negative characteristics of three other people. The more positively they judged those people, the more happy, enthusiastic, capable and emotionally stable they turned out to be themselves. People who judged others more positively also turned out to be more satisfied with their own lives.
